Overview

Auth features

The app catches and handles 4 different errors for user's input in text fields (Signup and Login VCs). These errors are presented for a user as a red message above the text fields.
The regular expression was used to validate an email address.

Password text field was designed with a secure eye that toggles dots and letters after tapping.

Post-auth View Controllers

Main VC contains a search controller. While typing prompt table view pops up with the delay 1 second (Combine's debounce operator).
Main VC has several sections with horizontal carousel scroll views (Compositional Layout).
Detail VC consists of 2 collection views (the second one is for paging), detail info view and custom stepper which increments quantity and increases a price of an item.
Profile VC provides the options of changing avatar and logging out.
